JOSEPH H. GIAR'I'H, OF ALTOONA, PENNSYLVANIA.

HEATING SYSTEM.

Application filed April 3, 1913.

T all whom it may concern:

Be it known that I, JOSEPH H. GIARTH, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented a new and useful Heating System, of which the following is a specification.

The present invention relates to improvements in heating systems, one object of the invention being the provision of a Vapor or steam heating system, in which when the pressure falls on the return side of the system due to condensation in a tank connected in the system, the flow of steam or vapor through the system into the tank is aided by the pressure of the atmosphere communicated to the supply side of the system at the boiler, thus producing a simple and economical vapor heating system.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure l is a diagrammatic view illustrating the present system. Fig. 2 is an enlarged View in elevation of the boiler and the adjacent pipes and circulating connections.

Referring to the drawings, the numeral 1 designates the steam or vapor generator, which may be of any type, the same having led therefrom, the main conducting pipe 2, which in the present instance has connected thereto and upstanding therefrom, the vertical risers or conduits 3, which have led therefrom the conduits 4: through the valved connection 5, which is disposed at the lowermost portion of the radiator 6. Led from the upper end of the radiator 6 at the opposite side to the pipe 4 is a conduit 7. Connected in this conduit is the usual automatic radiator valve 7', which is of the type that permits of the release of the pressure to permit of the filling of the radiator with the heating fluid, but which, as will presently appear, prevents the inflow of air due to the vacuum caused in the radiator by the cool- Specification of Letters Patent.

ing of the vapor and the consequent contraction thereof.

The pipe 8 is in communication with the vertical pipe 7 and is led to the auxiliary condensation receiving reservoir or tank 9, disposed at a level slightly above the dome of the boiler 1 and provided with the automatically controlled valved pipe 10, which provldes a means for releasing the pressure therein. The conduit 11 is led from the lowermost position of the tank 9, and through the check valve 12 to the conduit 13, which is 1n communication with the lowermost portion of the boiler 1 and constitutes the return conduit from the condensation receivlng tank 9. The check valve 12 is so constructed that it will close against pressure from the boiler but will permit of the flow of the condensationfiuid from the tank or reservoir 9 back into the boiler. Vertical risers 14 are connected to some of the radiators and to the return pipe 15, which is also led to the bottom of the boiler, thus permitting a complete circulation of the vapor through the system from the conduit 2 back to the boiler 1.

In order to provide a means whereby atmospheric air may be automatically admitted to the dome of the boiler 1 due to the pressure falling on the return side of the system and the condensation within the tank 9,. the conduit 16 is connected to and is in communication with the boiler, the same having connected thereto, the check valve controlled inlet 17, whose check valve 18, as clearly shown in detail in Fig. 2, is disposed to open, due to the reduction of pressure in the system to permit the air to enter, as indicated by the arrow Fig. 2, but which when the pressure is above atmospheric pressure within the boiler and the system, will be closed by the pressure within the boiler 1.

By this means it will be seen that the introduction of air to the system is directly at the boiler 1 and not through the radiators as is the usual practice, thus providing a means to compensate for the vacuum created in the system, at a point where the vapor and consequent heat will be maintained for the longest possible period within the radiators and circulating pipes of the system. By positioning such air inlet above the dome of the generator where the surroundator to the generator, a return pipe connect ed to the radiator, a condensation tank connected to said return pipe, an air outlet pipe connected to said tank and having an out- Wardly opening check valve therein, and an Copies of this patent may be obtained for air inlet pipe communicating with the steam space of the generator and having an in- Wardly opening check valve therein, said inlet pipe adapted to admit air into the gen-.

erator When the pressure therein fallsbelow that of the atmosphere. 7
